Low temps, no problem!

I wanted to be able to use the cart longer in the winter using 90ah 48v kit. I ended up insulating the battery bay, added 2 Seedling Heat Mats with Digital Thermostat Controller (https://a.co/d/0WOdcXa) along the sides on an EZGO RXV. I always make sure to plug in the mats after use, been keeping an eye on the temps with the app, no problems so far!
I use my cart at times through the winter. I wrapped my batteries with a seedling mat and using a digital thermostat also. Have checked in on them a few times when temperatures were under 32 degrees, batteries were nice a comfy above freezing.
